Developing energy storage is a key avenue for increasing India’s power system flexibility and the share of renewables and ultimately enabling India’s decarbonization, according to a study by the National Renewable Energy Laboratory (NREL).
The study team, comprising researchers from NREL’s recently launched Grid Planning and Analysis Center, evaluated storage growth under various technology, cost, policy, and regulatory scenarios, resulting in a range of trajectories for storage growth over the next three decades.
It said by 2030, energy storage capacity from these scenarios in India ranges from 50 to 120 GW and continues climbing to 180 to 800 GW by 2050. “Based on this modeling, 50 GW of energy storage by 2030 is a lower-bound estimate for the total storage market size in India, with most of this capacity expected to come from battery storage projects,” it said.
The study team also looked at scenarios that show which conditions lead to higher or lower energy storage deployment in India. When energy storage is barred from providing one of the value streams, storage deployment decreases.
“In the South Asia context, this means regulatory proceedings at the national and state levels may be needed to enable storage projects to participate as a source of both load and generation and to provide multiple grid services,” the study said.
